DETAILED DESCRIPTION OF EXAMPLES OF EMBODIMENTS

This patent application describes, among other things, examples of certain embodiments, and certain aspects thereof. Other embodiments may differ from the particular examples described in detail herein. Various embodiments are or include devices, apparatuses, machines, and methods for whitening teeth. In various embodiments, for example, light is used to whiten teeth. In many embodiments, a chemical is (e.g., also) used to whiten the teeth. In a number of embodiments, the light, or heat from the light, accelerates the whitening gel, for example, inside a closed system or mouth piece. Further various embodiments result in faster, more efficient, or longer lasting whitening, or a combination thereof, for instance, without the sensitivity of certain alternatives. Several examples are described herein, and different embodiments include one or more features from one or more of the examples described herein. All workable combinations are contemplated as different embodiments.

FIGS. 1 to 4 illustrate an example of an embodiment of a device or mouth piece for whitening teeth, device or mouth piece 100. In this embodiment, device 100 includes hand gesture control or sensor 105 (e.g., shown in FIG. 1) and LEDs 210 (e.g., shown in FIG. 2). In this embodiment, LEDs (light emitting diodes) 210 collectively form a light source that is located outside of the user's mouth when device 100 is properly positioned for operation, which is partially within the user's mouth. Light from LEDs 210 reflects off of polished surface or reflector 220 (e.g., shown in FIG. 2) to the user's teeth when device 100 is in operation.

In some embodiments, LEDs (e.g., 210) emit blue light. In certain embodiments, for example, the blue light has a wavelength of approximately 470 nm (nanometers) and is part of the “visible light spectrum”, which ranges from approximately 400 nm to 700 nm. In various embodiments, the light (e.g., from LEDs 210) is harmless or has no known negative effect to the human body. Further, particular embodiments allow the customer or user to use the device (e.g., 100) or method for less-lengthy whitening sessions compared to other systems. Even further, in various embodiments, the serum formula works in conjunction with the light (e.g., from LEDs 210) to speed up whitening. Further still, in some embodiments, serum is refrigerated, for example, until delivered to customers, for instance, in warehouse facilities. This maintains the potency of the chemical compounds in various embodiments.

As shown in FIGS. 3 and 4, in the embodiment illustrated, device or mouth piece 100 includes decorative front cover 401, decorative chrome band 402, wireless charging receiver PCB 403, motion detection lens 404, outer case 405, battery 406, LED sensors controls 407, gesture recognition and BLE PCB 408, self-cleaning UV LEDs and RGBW sensors 409, main hub 410 (e.g., that supports the PCBs), activating LEDs 210, LED reflector 220, clear LED water proof cover 411, and clear silicone mouth piece 412. Clear silicone mouth piece 412 is shown in FIG. 1 but omitted in FIG. 2 to better illustrate other components.

Activating Light Reflector

Summary of Problem

Prior designs of activating elements require a flexible PCB and light elements within the mouth cavity. These source elements were fixed with no modulation schemes or intensity controls. In various embodiments, light (e.g., from LEDs 210 shown in FIGS. 2 to 4) is used to whiten teeth (e.g., in conjunction with chemical treatment). In a number of embodiments, however, it is necessary or beneficial to avoid using too much light.

Solution

In a number of embodiments, a light reflection system (e.g., LEDs 210 and reflector 220) is controlled, for instance, via a pulse width modulation circuit (e.g., 808 shown in FIG. 8), for example, to control the grid and reflection pattern of a reflected light source (e.g., 210 or 210 and 220). In some embodiments, light reflection patterns are designed to change the intensity of the light waveform, for instance, by modifications to the peak output. Further, in particular embodiments, control mechanisms are done via wireless controls (e.g., Bluetooth), hand gestures (e.g., EMF—Electro-Magnetic Fields, IRF—Infrared Fields), or both. Still further, in certain embodiments, modulation schemes allow for power schemes of 0-100%, for example. An example of a device is device 100 shown in FIGS. 1 to 4, for instance. FIG. 8 is a schematic or block diagram showing how different electronic components are connected to each other in certain embodiments. Other embodiments may differ. Not necessarily every electrical connection or component is shown.

In various embodiments, the components of a reflector (e.g., 220) include a (e.g., chromed) reflective surface, for example, with an angled edge, for instance, to reflect light (e.g., from one or more LEDs, for instance, 210). Further, some embodiments, for example, include a reflector PCB, for example, that reflects light to (e.g., each of), for instance, six (6) quadrants of teeth. These quadrants may be, for example, in some embodiments: Center Top, Center Bottom, Left Top, Left Bottom, Right Top, and Right Bottom. In certain embodiments, the (e.g., LED) reflector PCB includes or consists of 6 arrays (e.g., of LEDs, for instance, 210), for example, independently controlled, for instance, to light each of the 6 quadrants. In turn, in some embodiments, the arrays or LEDs (e.g., 210) are driven, for example, by PWM (Pulse Width Modulation, e.g., 808), for instance, to alter the individual light intensity (e.g., in each quadrant). Further, in particular embodiments, the reflector (e.g., 220) is placed over a (e.g., flex) PCB.

In various embodiments, the reflector (e.g., 220) is made out of polished steel, chrome plating, or polished brass, as examples. Further, in a number of embodiments, the reflector (e.g., 220) is designed (e.g., shaped) to reflect light from outside of the users mouth (e.g., from LEDs 210), for example, evenly, for instance, throughout the center, left, and right sides of the user's mouth. In various embodiments, the light source (e.g., 210) is external to the mouth (i.e., when mouth piece 100 is properly positioned for treatment of the user's teeth) and the reflector (e.g., 220) reflects and distributes the light within the mouth. In a number of embodiments, this provides controlled distribution of the light, for example, in contrast with certain prior alternatives that do not guide the light at all.

In a number of embodiments, the light source (e.g., 210) is or includes LEDs, for example, discrete, RGB (red, green, blue), or both, for instance, which allows for variation in the frequency of the light in some embodiments. Further, an example of the pulse width modulation circuit is shown in FIG. 8 (e.g., 808 or TLC59108, for instance, connected to the LED arrays, for example, 210). In contrast with pulse width modulation (e.g., 808), other alternatives are On/Off. In a number of embodiments, the pulse width modulation circuit (e.g., 808) controls the grid and reflection pattern of the reflected light source (e.g., 210). In certain embodiments, for example, the PWM circuit (e.g., 808) works with the on-board intelligence of the mouth piece (e.g., 100). When the teeth are scanned, in some embodiments, an algorithm determines (e.g., based on the timer and shade value received for the quadrant), what duty cycle to set (e.g., for each quadrant), for instance, when the treatment begins. Due to the flexibility of the modulation scheme, in particular embodiments, the algorithm may be further tuned, for example, to generate modulation patterns to further enhance the treatment process, for instance, by the dynamic variation of the duty cycles for each quadrant. In certain embodiments, peak output (e.g., in terms of millicandela or mcd), or the intensity of light (e.g., from 210) or dynamic variations is controlled, for example, by the algorithm, driven by the PWM (e.g., 808), or both.

Further, in a number of embodiments, wireless control serves as a mechanism to utilize a third-party wireless device, for example, for setup, control, additional algorithms for analysis and treatment, or a combination thereof. Still further, in some embodiments, hand gestures are detected (e.g., via sensor 105) via electro-magnetic field (EMF) or infrared (IR), for instance, array 805 shown in FIG. 8), as examples. With an EMF solution, for instance, multiple antennas are set up in an array (e.g., sensor 105), in some embodiments, generating a field which can be manipulated by passing through the field with a hand or finger. In a number of embodiments, the antenna field is measured by the transmitter, and when a change is detected, the logic analyzes the condition. In various embodiments, for instance, the order of state changes determines the gesture to be achieved. For example: in a two antenna system (e.g., of sensor 105), if the left antenna triggered a state change, followed by the right antenna, the logic would assume that someone was swiping from left to right. Further, in certain embodiments, an IR solution works (e.g., in a similar way) using an array of IR transmitters (e.g., of sensor 105, for example, 805), for example, with an IR receiver centrally located within the array (e.g., 105 or 805). The example above also holds true for the IR solution (e.g., 805) in some embodiments. In a number of embodiments, hand gestures are read or detected by or at a mouth piece (e.g., 100, for instance, via sensor 105). Further, certain embodiments provide a simplified way to interact with a smart connected device. In particular embodiments, however, use of an app is avoided.

Various embodiments are or include a device (e.g., 100) for whitening teeth. Further, different embodiments include a light reflection system (e.g., light source 210 and reflector 220), a pulse width modulation circuit (e.g., 808 shown in FIG. 8), or both. Still further, in particular embodiments, the lighting system (e.g., 210) or light reflection system (e.g., 210 and 220) is controlled, for example, by the pulse width modulation circuit (e.g., 808). Even further, various embodiments include a reflected light source (e.g., 210 or 210 and 220). Moreover, in some embodiments, the pulse width modulation circuit (e.g., 808) controls a grid, a reflection pattern of the reflected light source, or both. Further still, in some embodiments, light reflection patterns are controlled, for instance, to change intensity of a light waveform, for example, by modifications to a peak output.

In various embodiments, a device (e.g., 100) for whitening teeth of a user includes a light source (e.g., 210) and a light delivery mechanism (e.g., reflector 220), for example, that delivers light from the light source (e.g., 210) to the user's teeth. In some such embodiments, for instance, the light source (e.g., 210) is driven by a pulse width modulation circuit (e.g., 808 shown in FIG. 8). Further, in a number of embodiments, the device (e.g., 100) includes a light source (e.g., 210) and a pulse width modulation circuit (e.g., 808) that drives the light source (e.g., 210). Still further, in various embodiments, the light source (e.g., 210) is located outside the user's mouth, the mechanism (e.g., reflector 220) that delivers light from the light source (e.g., 210) to the user's teeth is located within the user's mouth (i.e., when the device, e.g., 100, is in use), or both. Further still, in various embodiments, the mechanism that delivers light from the light source (e.g., 210) to the user's teeth is a reflector (e.g., 220), the light source includes LED's (e.g., 210), or both. Even further, in particular embodiments, the light source (e.g., 210) includes multiple (e.g., arrays of) light sources (e.g., 210), the multiple (e.g., arrays of) light sources are each independently controlled, the multiple (e.g., arrays of) light sources (e.g., 210) are each driven by pulse width modulation (e.g., 808), or a combination thereof, for example. Even further still, in some embodiments, the multiple (e.g., arrays of) light sources (e.g., 210) each primarily illuminate a different quadrant of the user's mouth, intensity of the multiple (e.g., arrays of) light sources (e.g., 210) is controlled, intensity of the light source (e.g., 210) is controlled (e.g., via PWM 808), or a combination thereof, as examples.

In a number of embodiments, the light source (e.g., 210) illuminates various (e.g., six) quadrants of the user's teeth. Further, in some embodiments, the light delivery mechanism (e.g., reflector 220) delivers light (e.g., from the light source, for instance, 210) to (e.g., six) quadrants of the user's teeth. For example, in particular embodiments, the (e.g., six) quadrants of the user's teeth are or include: Center Top, Center Bottom, Left Top, Left Bottom, Right Top, Right Bottom, or a combination thereof, as examples. Still further, in particular embodiments, the light delivery mechanism (e.g., 220) has an angled edge. Further still, in some embodiments, the device (e.g., 100) for whitening teeth further includes a printed circuit board. Even further, in certain embodiments, the light delivery mechanism (e.g., 220) is located over the printed circuit board, the printed circuit board is flexible, or both. Even further still, in particular embodiments, the light delivery mechanism (e.g., 220) delivers light (e.g., substantially evenly) from the light source (e.g., 210) to the user's teeth. In this context, “substantially” means to within plus or minus 25 percent.

In some embodiments, the light source (e.g., 210) is an RGB light source. Further, in some embodiments, the device (e.g., 100) is controlled wirelessly, for example, using a separate electronic device. For instance, in certain embodiments, the light source (e.g., 210), in particular, is controlled wirelessly using a separate electronic device.

Visible Light Shade Detection System

Summary of Problem

Until now, the accuracy of determining the color or shade of a user's teeth has been a manual process, using both personal observation and shade guides provided by the dental community.

Solution

In various embodiments, the process of identifying the color or shade of teeth is automated. Further, in a number of embodiments, accuracy is improved over previous subjective methods in which color or shade was a matter of perspective. Still further, in various embodiments, (e.g., high accuracy) color sensors (e.g., 230 shown in FIG. 2) are used. In some embodiments, for example, these color sensors (e.g., 230) utilize red, green, blue, and white (RGBW) detection elements, as examples. Some embodiments are calibrated by using warm and cool colored white light sources, for instance (e.g., LEDs 210 shown in FIG. 2). In various embodiments, the sensors (e.g., 230) sense or analyze the reflected light from the target surface. In some embodiments, for example, the sensors (e.g., 230) sense color, while in other embodiments, the sensors (e.g., 230) sense shade, and in certain embodiments, the sensors (e.g., 230) sense both color and shade (e.g., of the teeth). Further, in certain embodiments, color or shade readings are output, for instance, over i2c, for example, in the value which references the visible light spectrum (390-700 nm). In a number of embodiments, the data is injected into a learning algorithm, for instance, running on a Host processor. Still further. In particular embodiments, this Host processor, for example, calculates the recommended treatment. Treatment settings for the Activating element are automatically populated, in some embodiments, for instance, when the device (e.g., 100) is in autonomous mode. Even further, in certain embodiments, the data is output wirelessly (e.g., via Bluetooth), for example, connecting to an App, to the cloud (e.g., for detailed analysis), or both.

In various embodiments, calibration cool and warm light source elements (e.g., LEDs 210 shown in FIG. 2) are used in the calibration of the (e.g., color) sensor (e.g., 230). In some embodiments, for example, the warm and cool elements represent the color temperature of white light in the frequency spectrum necessary to achieve an accurate measurement of color. In particular embodiments, six (e.g., color) sensors (e.g., 230) are used, for example, in the locations shown. In some embodiments, RGBW sensors are used. Further, in some embodiments, six sensors (e.g., 230) translate to six individual grids, for example, thee on top and three on the bottom. In certain embodiments, for instance, the configuration is designed to assign multiple quadrants to the mouth for analysis. In various embodiments, for example, the more sensors (e.g., 230), the more accurate the measurements will become, for instance, within each quadrant. In various embodiments, color data is collected from the teeth and used to control a teeth-whitening process, for instance, using a computer or a processor to analyze the color data. Further, particular embodiments use a computer or a processor to analyze the color data and control a teeth-whitening process (e.g., using the output from the computer or processor). Even further, in a number of embodiments, the “reflected light” is light originating from the teeth-whitening device (e.g., 100, for instance, from LEDs 210).

Certain embodiments use a learning algorithm to analyze color data, for example, to determine a treatment process. In a number of embodiments, for example, a recommended treatment includes, for example, an intensity, a duration, or both (e.g., of light emitted from LEDs 210). In various embodiments, the recommended treatment is different for different teeth. In various embodiments, the recommended treatment is calculated or determined, for example, based on compiled user data. Further, in some embodiments, a learning algorithm is used, for example, to allow the user to be hands off, let the hardware control the treatments, or both. Other embodiments, however, do not use a learning algorithm. Still further, different embodiments, use wireless or wired control, for example, of the hardware mechanisms.

Particular embodiments include, for example, sensor initialization, calibration, measurement, and data output. In some embodiments, an algorithm receives data output, calculates color, compares color to all quadrants, sets timer and peak intensity to each quadrant (e.g., based on shade color and delta between quadrants), or a combination thereof. In some embodiments, for example, data is output from the sensors (e.g., 230) over i2c to the host processor. Further, in some embodiments, data is input into the learning algorithm over I2c, for example, from sensors (e.g., 230), the cloud, and a smart device, for instance, running an application. Still further, in particular embodiments, sensor data and user data (e.g., from the cloud) is input into the learning algorithm. Examples include, in some embodiments, shade, color, serum strength, number of treatments per day, or a combination thereof. Even further, in some embodiments, feedback that is input into the learning algorithm to enable it to learn includes treatment times (e.g., in minutes), intensity, number of uses, shade data (e.g., at start of use to end of use), or a combination thereof. Even further still, in particular embodiments, output that is received from the learning algorithm includes device settings for treatment cycles, for example, intensity, duration, notifications (e.g., in the app), or a combination thereof. Moreover, in certain embodiments, output is used for treatments, enhancing the algorithm, or both. In various embodiments, treatment settings are or include intensity, duration, or both (e.g., of each quadrant).

Certain embodiments include a host processor, for example, a Master i2C controller for peripherals. Further, particular embodiments include an activating element, for example, blue LEDs (e.g., 210). Further still, in some embodiments, information is automatically populated, for example, from the hardware or from the App. Even further, some embodiments include an autonomous mode, for example, that uses the machine learning, for instance, to set up the treatments. Still further, in some embodiments, other modes include gesture control, shake and wake, autonomous, wireless, or a combination thereof, as examples.

In various embodiments, a device (e.g., 100) for whitening teeth of a user includes one or more (e.g., color) sensors (e.g., 230 shown in FIG. 2), for example, used to analyze reflected light from a target surface of the teeth, for instance, to recommend a whitening treatment for the teeth. In a number of embodiments, for example, the device (e.g., 100) produces the light (e.g., with LEDs 210) that becomes the reflected light when reflected by the target surface of the teeth. Further, certain embodiments are or include a device (e.g., 100) for whitening teeth of a user that includes a (e.g., color or shade) sensor (e.g., 230), for instance, that detects color or shade of the teeth of the user. In a number of embodiments, a device (e.g., 100) for whitening teeth of a user detects color of the teeth of the user in particular. Still further, in various embodiments, a device (e.g., 100) for whitening teeth of a user collects color data from the teeth and controls a teeth-whitening process (e.g., operation of LEDs 210) using the color data.

In a number of embodiments, the device includes a computer or a processor (e.g., local or remote, in different embodiments), for example, that uses the (e.g., color, shade, or both) data, analyzes the data, controls the teeth-whitening process, or a combination thereof, as examples. In some embodiments, the device (e.g., 100) further includes a light source (e.g., 210), the device (e.g., 100) shines light on the teeth to whiten the teeth, or both. Further, in some embodiments, the device (e.g., including mouth piece 100) uses the color, shade, or both, of the teeth to determine how to whiten the teeth. Still further, in certain embodiments, the device uses the light reflected by the teeth to determine how to whiten the teeth. Even further, in particular embodiments, the device (e.g., 100) emits the light (e.g., with LEDs 210) that is reflected by the teeth, for instance, that is used by the device (e.g., including mouth piece 100) to determine how to whiten the teeth. Further still, in some embodiments, the device uses color, shade, or both, of the teeth to determine intensity of light to shine (e.g., with LEDs 210) onto the teeth, the device (e.g., including mouth piece 100) uses light reflected by the teeth to determine intensity of light to shine (e.g., with LEDs 210) onto the teeth, or both.

In some embodiments, the device (e.g., 100) for whitening teeth of a user includes cool light source elements (e.g., LEDs 210 shown in FIG. 2). Further, in some embodiments, the device (e.g., 100) includes warm light source elements (e.g., 210). Some embodiments include both. Moreover, in various embodiments, the light source elements (e.g., 210) are used to calibrate the device (e.g., 100). Still further, in some embodiments, the device (e.g., 100) for whitening teeth of a user includes (e.g., multiple) (e.g., color) sensors (e.g., 230). For example, in particular embodiments, different sensors (e.g., 230) sense light in different areas of the (e.g., user's) mouth. In certain embodiments, for instance, different (e.g., color) sensors (e.g., 230) sense light in different quadrants of the mouth. Further still, in a number of embodiments, the device includes a processor, for example, that controls the device (e.g., 100). For instance, in some embodiments, the processor controls the intensity of light produced (e.g., with LEDs 210) by the device (e.g., 100). Even further, in some embodiments, the processor analyzes reflected light from the teeth. For example, in particular embodiments, the processor analyzes color, shade, or both, of the teeth. Even further still, in certain embodiments, the device for whitening teeth of a user includes or uses a learning algorithm. For example, in some embodiments, the device uses the learning algorithm to analyze the (e.g., color) data, to control the teeth-whitening process (e.g., light from LEDs 210), or both.

Self Cleaning Mouth Guard

Summary of Problem

Prior designs in production offer a washable surface which leaves opportunities to grow bacteria and to cause infections within the user's mouth.

Solution

In a number of embodiments, ultraviolet light sources, for example, are embedded within the mouth guard, for instance, to clean the mouth piece when the user has finished using the product. For example, FIG. 2 shows UV light source elements 240 located in device, mouth piece, or mouth guard 100. In FIG. 2, two UV light source elements 240 are visible, but in some embodiments, a third UV light source element is present opposite the UV light source element 240 that is on the right side of FIG. 2. In some embodiments, the UV light source elements (e.g., 240) shine ultraviolet light on up to 100 percent of the mouth guard (e.g., 100) or the portion of the surface of the mouth guard that is in the mouth of the user when in operation. In various embodiments, utilization of a wireless charging system, and safety mechanisms to protect the users from damaging their eyes during the clean cycle, require that the mouth guard (e.g., 100) be successfully docked in an enclosure and the enclosure cover closed. FIG. 5 shows an example of an enclosure, enclosure 500, with cover 501 closed. In some embodiments, for example, the enclosure (e.g., 500) has a shape of a circular cylinder (e.g., as shown, for instance, cylindrical body 510), for example, with flat ends (e.g., at top and bottom) that are perpendicular or substantially perpendicular to a centerline of the cylinder. FIG. 5 shows excess cable storage 502, micro USB power connection 503, and cover hinge 505. FIG. 6 shows enclosure 500 with cover 501 open and mouth piece 100 docked inside enclosure 500 (e.g., for charging, sterilization, storage, or a combination thereof). In some embodiments, the cover (e.g., 501) has embedded charging circuits and BLE, magnetic latching, or a combination thereof, as examples. Further, FIG. 6 shows swing out serum wand and cable storage or swing door 660 (e.g., magnetic latching). In some instances herein, the word “device” refers to the mouth piece (e.g., 100) only, but in other instances, the word “device” may include the enclosure (e.g., 500) or charger. Further still, in certain instances, the word “device” may include a computing device, for example, that is in communication with the mouth piece (e.g., 100). Still further, these alternatives are not necessarily exhaustive.

In a number of embodiments, when the mouth piece (e.g., 100) has been successfully docked (e.g., in enclosure 500, for instance, as shown in FIG. 6), and the enclosure cover (e.g., 501) closed (e.g., as shown in FIG. 5), Hall effect sensors, for example, on two sides of the enclosure, trigger or enable the wireless charging system. This is an example of a safety mechanism that protects the user from eye damage from the ultraviolet light source. Once the transmitter has been enabled, in some embodiments, wireless charging protocol begins to transmit to the receiver, for instance, first checking for foreign objects in the path between the mouth guard (e.g., 100) and the enclosure (e.g., 500). In certain embodiments, once no objects are detected and the receiver has acknowledged communication, a timer on the receiver will trigger the UV elements (e.g., 240), for instance, for a particular time (e.g., X.xxx mS), which is a programmable timer in some embodiments. In particular embodiments, the UV elements (e.g., 240) are powered (e.g., directly) from the receiver side bridge and receiver, for instance, which keeps the elements (e.g., 240) from turning on accidently.

Various embodiments (e.g., of a teeth-whitening device, for instance, 100) include one or more ultraviolet light sources (e.g., 240), for example, LEDs, for instance, to clean (e.g., sterilize) the teeth-whitening device (e.g., mouth piece, for instance, 100). Further, in various embodiments, the “ultraviolet light sources” (e.g., 240) are located in the wireless charging system, are driven by the wireless charging system, operate (e.g., sterilize or apply UV) while charging the (e.g., teeth-whitening) device (e.g., 100), or a combination thereof. Still further, certain embodiments include a safety mechanism, for example, to protect users from damaging their eyes during the cleaning cycle. Even further, particular embodiments, require that the mouth guard (e.g., 100) be successfully docked in an enclosure (e.g., 500) or that the enclosure cover (e.g., 501) be closed, for example, before charging the device (e.g., mouth guard 100), emitting UV (e.g., from UV lights 240), starting the cleaning cycle, or a combination thereof. Further still, some embodiments use one or more Hall effect sensors, for example, to trigger or enable a wireless charging system, a UV system (e.g., UV lights 240), or a sterilization or cleaning system (e.g., UV lights 240), as examples. The drawings show examples. In different embodiments, various wireless charging protocols are used.

Some embodiments include a receiver, for example, an Infineon solution. Further, certain embodiments check for foreign objects in the path between the mouth guard (e.g., 100) and the enclosure (e.g., 500), for example, by detecting heat changes, current, or both. Still further, in some embodiments, the receiver acknowledges communication using Qi. Even further, some embodiments include a timer, for example, that controls the amount of time that the UV elements (e.g., 240) or cleaning system is operated. In certain embodiments, the timer is adjustable, for instance, from 1-30 minutes. Even further still, in particular embodiments, the timer is set automatically, for example, using machine learning.

Various embodiments of a device for whitening teeth include a mouth piece (e.g., 100 shown in FIGS. 1 to 4, 6, and 7) and an ultraviolet light source (e.g., 240 shown in FIG. 2), for example, to clean the mouth piece (e.g., 100), for instance, when the user has finished using the device (e.g., 100). In a number of embodiments, for example, the mouth piece (e.g., 100) is cleaned with the ultraviolet light (e.g., from 240) while the device (e.g., 100) is charging. Further, in some embodiments, an ultraviolet light source (e.g., 240) sterilizes the mouth piece (e.g., 100). Still further, in particular embodiments, the device or ultraviolet light source (e.g., 240) sterilizes the mouth piece (e.g., 100) when the mouth piece (e.g., 100) is not in the user's mouth. Further still, in a number of embodiments, the device or ultraviolet light source (e.g., 240) sterilizes the mouth piece (e.g., 100) when user has finished using the device (e.g., 100) for whitening the user's teeth, for example, when the mouth piece (e.g., 100) is charging. As used herein, “sterilizes” does not necessarily mean complete sterilization, but many embodiments significantly reduce the quantity of harmful or potentially harmful microorganisms from at least part of the device or mouth piece (e.g., 100).

A number of embodiments of a device for whitening teeth include a mouth piece (e.g., 100) and a sterilizer, for example, that sterilizes the mouth piece. In various embodiments, for instance, the sterilizer includes an ultraviolet light source (e.g., 240), the sterilizer sterilizes the mouth piece (e.g., 100) when the mouth piece is not in the user's mouth, the sterilizer sterilizes the mouth piece (e.g., 100) when user has finished using the device (e.g., 100) for whitening the user's teeth, the sterilizer sterilizes the mouth piece (e.g., 100) when the mouth piece (e.g., 100) is charging, or a combination thereof, as examples.

Even further, in various embodiments, the ultraviolet light source (e.g., 240) operates when the user has finished using the device (e.g., 100) for whitening the user's teeth, for example, only when the user has finished using the device (e.g., 100) for whitening the user's teeth. Further still, in some embodiments, the ultraviolet light source (e.g., 240) operates when the device (e.g., 100) is charging (e.g., in enclosure 500), for instance, only when the device (e.g., 100) is charging. Even further still, in various embodiments, the device (e.g., 100) for whitening teeth includes the ultraviolet light source (e.g., 240) and the ultraviolet light source includes at least one LED, for example, that emits the ultraviolet light.

Mouth Detection

Summary of Problem

Prior whitening systems are required to be plugged in or turned on before the device has been put into the user's mouth.

Solution

Various embodiments include one or multiple sensors or arrays that enable the function of the device (e.g., 100) once in the user's mouth. In some embodiments, for example, an EMF (Electro-Magnetic Field) Array (e.g., EMF field sensor or array 250 shown in FIG. 2) is placed (e.g., at three points) around the mouth guard (e.g., 100). In some embodiments, for instance, this requires the device (e.g., 100) to be in the mouth before operation. In addition, in particular embodiments, the array (e.g., 250) is enabled by using a wake on pick up feature, for instance, of an accelerometer (e.g., 811 shown in FIG. 8), to wake the device (e.g., 100) from a deep sleep. In some embodiments, hand gestures (e.g., detected via sensor 105) or the use of the App over a wireless (e.g., Bluetooth) connection begin the treatment cycle (e.g., operation of LEDs 210).

In prior whitening systems that were required to be plugged in or turned on before the device has been put into the user's mouth, this was a simple way to power the device, but there was no: intelligence for the user, modes of treatment, or a real sense of travel and portability, as examples. In some embodiments, a user can put the device (e.g., 100) in her mouth and then turn it on or plug it in, but in particular embodiments, this may impact the results. In certain embodiments, for example, the timer starts once the activating LEDs (e.g., 20) are on. In various embodiments, an electro-magnetic field (EMF) array (e.g., via EMF field sensor or array 250 shown in FIG. 2) is used or included in a teeth-whitening device, for example, to detect whether the device (e.g., 100) is in someone's mouth. Further, in particular embodiments, the array (e.g., 250) is enabled by using a wake on pick up feature or an accelerometer (e.g., 811) to wake the device. In certain embodiments, for example, the accelerometer (e.g., 811) goes to an interrupt pin that can wake up the primary processor. In some embodiments, the device (e.g., 100) goes into a deep sleep, for example, an extremely low current state, for instance, to extend battery (e.g., 406 shown in FIGS. 3 and 4) life. Still further, in various embodiments, hand gestures (e.g., detected by sensor 105) are used. For example, in particular embodiments, hand gestures may include swiping (e.g., from left to right), pressing, finger twirling (e.g., like stirring coffee), or a combination thereof, as examples. Even further, in certain embodiments, wireless communication (e.g., Bluetooth) connects the device (e.g., 100) to a smart device, for example, a smart phone. In various embodiments, to begin a treatment cycle (e.g., energize LEDs 210), a user may use the App (e.g., on the smart device), use a gesture (e.g., detected by sensor 105), shake the device (e.g., mouth piece 100, accelerometer 811, or both), or a combination thereof, as examples.

In various embodiments, a device (e.g., 100) for whitening teeth includes at least one sensor or array (e.g., EMF sensor or array 250) that enables function of the device (e.g., 100) once the device (e.g., 100) is in the user's mouth and that requires the device (e.g., 100) to be in the mouth before operation. In a number of embodiments, for example, at least one sensor (e.g., 250) senses whether the device (e.g., 100) is in the user's mouth, turns on the device (e.g., 100) when the device is placed in the user's mouth, allows the device (e.g., 100) to operate only when the device (e.g., 100) is in the user's mouth, or a combination thereof.
